Peer reviewed Peer reviewed

Steinmetz, Jean-Paul; Brunner, Martin; Loarer, Even; Houssemand, Claude – Psychological Assessment, 2010
The Wisconsin Card Sorting Test (WCST) assesses executive and frontal lobe function and can be administered manually or by computer. Despite the widespread application of the 2 versions, the psychometric equivalence of their scores has rarely been evaluated and only a limited set of criteria has been considered. The present experimental study (N =…

Clarifying Problems and Offering Solutions for Correlated Error when Assessing the Validity of Selected-Subtest Short Forms
Peer reviewed Peer reviewed

Girard, Todd A.; Christensen, Bruce K. – Psychological Assessment, 2008
The correlation between a short-form (SF) test and its full-scale (FS) counterpart is a mainstay in the evaluation of SF validity. However, in correcting for overlapping error variance in this measure, investigators have overattenuated the validity coefficient through an intuitive misapplication of P. Levy's (1967) formula. The authors of the…

Corrected Estimates of WAIS-R Short Form Reliability and Standard Error of Measurement.
Peer reviewed Peer reviewed
Axelrod, Bradley N.; And Others – Psychological Assessment, 1996
The calculations of D. Schretlen, R. H. B. Benedict, and J. H. Bobholz for the reliabilities of a short form of the Wechsler Adult Intelligence Scale--Revised (WAIS-R) (1994) consistently overestimated the values. More accurate values are provided for the WAIS--R and a seven-subtest short form. (SLD)

Selective Reminding Test Short Form Administration: A Comparison of Two through Twelve Trials.
Peer reviewed Peer reviewed
Smith, Renee L.; And Others – Psychological Assessment, 1995
The clinical utility of using fewer than 12 trials of the Selective Reminding Test, a task to assess verbal memory, was studied with 100 cardiac patients and 100 brain injury patients. Results suggest that as few as 6 trials might be adequate, providing information consistent with that from 12 trials. (SLD)

Cross-Cultural Normative Assessment: Translation and Adaptation Issues Influencing the Normative Interpretation of Assessment Instruments.
Peer reviewed Peer reviewed
Geisinger, Kurt F. – Psychological Assessment, 1994
Issues affecting measures that are translated or adapted from an initial language or culture to a new one are described. Notions of test validation, fairness, and norms are addressed, and it is argued that such adaptations may be necessary when assessing members of subpopulations of the U.S. culture. (SLD)
